IMPROVED APPARATUS FCR WELDING CHAIN-LINKS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern:

Be it known that I, HENRYREYNOLDS, of Aurora, in the county of Cayuga,and State of New York, have invented certain new and useful Improvementsin Machines for XVelding GhninvLinks; and I do hereby declare thefollowing to be a full, clear, and exact description of the same,reference being had to thel accompanying drawings, making e part of thisspecif fr ,g Figure l represents a-front elevation of the machine.

Figure 2 represents n vertical section through the seme, teken at 'theline C D of tig. 1.

Figure -3 representsa. horizontal section through the machine, taken etthe line A-B of fig. i'.

Figures 4 and 5 represent the anvil and hammerdies, for welding andiinishing the links, on an enlarged scale.

ASimilar letters of reference, where they occurin the separate figures,denntelihe parts ofthe machine in all of the drawings.

. The object and purpose of myinvention are to weld nplinks in formingchains, by a series of graduated blows between dies of peculiar form,and so that no fin shallbe formed at the line of meeting of the dies,and thus weld and iinish the links at the Sametime.

, To enable others skilled in the art to make and use my invention, Iwill proceed to describe the saine with reference to the drawings.

In a suitable housing or trame, E, is arranged n crank oreccentrie-shnft,l which may be turned or stopped by an endless beltrunning upon the first pulley G, or shipping it upon the loose one H, asthe ense may be.

On the end of said cinnlshaft, opposite to the fastand Iloose pulleys,is a balance ily-wheel, l', for giving Stea'diness ot' motion to theshaft, and to the hammer J, connected to it by the pitman or crank-rodK, said ,hammer moving upon guides or ways, L, in the hous- 1 the underpart oi' the hammer J, e port-ion of the shaping-die is formed, betterseen nt` a a, iigxfi, this die working, not against, but into the underor Mvll-dle o c, will he explained. l Upon n shaft, M, supported in thehousingor frame E and at or nea-r the lower end thereof, there is en.gtlju'table cam, N, which can he set, and then fastened to said shaft. gn l.

And upon one of the ends of this shaft M, th'ere is arranged nhand-lever, O, which can, if found desirable, he made adjustable by itsset-screw e taking into one of a series of holes in en are, i', 'scentedto the Shsfb M.. ,j

Upon the cam N, rests the anvil P, which l cnn he raised up or let downby said cam,tbrou h' the lever O.

Theicnnubkis slipped upon the shaft M; and when wdjusted, is fastened by :i set-screw or other device,f, and by shift-ing the cam or-the leverupon the shaft,

v and then fastening them, the anvil can-gzberaised ce kept at itswnrkingfposition with less oni-more motion, as the character ot' thework muy require.

The anvil movesand is guided initsmovementsby v the die c, and theirline of contet is within the under die, leaving myspace or `joint-'in wiich nu objectionable fin or die-mark cnn he made.y Thehammer does nottouch the anvil, but the hammerdieeriters .into the anvildie, and .whenthe twodies pproach each other as near as they can, the spac'- ruled-:hythe two unequal cavities in the dies' makes complete circularcavity,in'cross-section, for giving that'nferm to the welded link, asseen in ig. 4.

The hammer and' sdie move v space, which is defined by thee-mnh on theshaft F.

The anvildie` is moved up gradually, so that the first blows of thehammer-die maybe light, just reaching the metal to ne welded, out bybringing down the lever or raising the cam N, the miv-il and its die arebrought nearer and negre to the hammer-die, and thus receiving increasedo V "adu'eted blows, until the hammer-die entersijhe anvil-die, and notonly com.- pletcs the weld, lbut shapes and neatly finishes the throughsuniform 'v link, so that there is scarcely :t iinor "a, die-morirlperceptible.J

Dierent dies may bensed in the machine' for difv'ferent-sized links, andVthe 'adjust-ment of the cam is suoli that vthe anvil'eflie vcan he soaccuratelyraised that the upper die will work into itwithout jamming orsticking. From the pofntsn, of the anvil -die c, it flaresoutward,1sothat the upper die is readily worked into it, withbut-nnydanger of marring it.

I amnware that hammers or drop-dies have been used,'fa.iid thntmvilswthdies` in them havealso been used. 'These Ido not e-lim; hut hnvingthusfully described my invention,
